Expression Encoder 4 Pro缺少音频编解码器 [英] Expression Encoder 4 Pro missing audio codecs

问题描述

我使用IIS Smooth Streaming从Expression Encoder 3升级到Expression Encoder 4 Pro。  当我查看"关于"时它说它是一个完全许可的副本。  我尝试过激活EE4 Pro，但它告诉我它已经被激活了。

I upgraded to Expression Encoder 4 Pro from Expression Encoder 3 with IIS Smooth Streaming.  When I look in the "About" box it says that it is a fully licensed copy.  I tried Activating EE4 Pro, but it told me it was already activated.

我的问题是我在实时流媒体中没有看到使用WMA Lossless的选项， WMA语音或AAC编解码器。   Audio的下拉列表仅列出WMA和WMA Professional。  我可以选择使用IIS Smooth Streaming
和H.264编解码器进行编码，所以我知道我安装了正确版本的Expression Encoder。

My problem is that I do not see the option, when in live streaming, to use the WMA Lossless, WMA Voice or AAC codecs.  The drop down list for Audio only lists WMA and WMA Professional.  I do have the option to encode using IIS Smooth Streaming and the H.264 codec, so I know that I have the correct version of Expression Encoder installed.

谢谢！

推荐答案

实时编码不支持WMA无损或WMA语音，仅支持AAC在IIS平滑流媒体中使用h.264视频。

Live encoding does not support WMA lossless or WMA voice, and AAC is only supported in IIS Smooth Streaming with h.264 video.
